Diesel engines are more fuel efficient than gasoline engines. That is to say, diesel engines get better “gas” mileage than comparably sized gasoline powered engines. There are two reasons why. First, diesel is a better fossil fuel than gasoline with respect to energy density. And second, diesel

How efficient are engines? Combustion engines are stupefyingly inefficient. Most diesel engines do not even have a thermal efficiency of 50%. Of every gallon of diesel burned by a combustion engine, less than half of the energy generated becomes mechanical energy. That is to say, of the energy produ

Rentar Fuel Catalyst Fuel Efficiency Increases on Marine Application Diesel Burning Engines Almost Unbelievable The Rentar Fuel Catalyst has produced industry-standard-changing results in both field and lab tests when used to reduce emissions and increase diesel fuel combustion efficiency on engines

Generators and the Rentar Fuel Catalyst: Significant Diesel Consumption Reduction Coupled with Substantial Run-Times Equate to Exponential Fuel Cost Savings On generators, the Rentar Fuel Catalyst has proven to cut fuel costs, on average, by between 7 and 12 percent. And the Rentar Fuel Catalyst has

For more than 10 years I have witnessed tens of thousands of dollars saved on fuel; a substantial reduction in emssions, and extended engine life of equipment installed with a Rentar Fuel Catalyst
